摘要： Various methods are presented that facilitate the connection of a speaker system to a separate functional system. In some embodiments, the connection is made through a male and female connector designed to twist into a locking position. In other embodiments, the connection is made by a guided connection with beveled edges to facilitate correct alignment of the speaker system. In still other embodiments, the connection includes mechanical locking mechanisms with a quick disconnect feature. In other embodiments, the connection also facilitates transmission of electrical signals through the connector.

摘要： A wireless communication device and a wireless communication method capable of curbing occurrence of latency even when performing wireless communication at predetermined time intervals are provided. MIDI data is transmitted and received by communication (B) performed through a wireless module during an intermission between communications (A) performed at predetermined time intervals through the wireless module. Accordingly, a communication speed for wireless communication is improved. Therefore, compared to a case in which wireless communication is performed by only the communication (A), MIDI data can be quickly transmitted and received, and thus occurrence of latency can be curbed.

摘要： With reference to FIG. 7a the present invention relates to transducer apparatus (200) for use with a reed instrument (201) having an air chamber (15) forming a resonant cavity whose resonance characteristics are controlled by opening and closing of tone holes (17A, 17B) connecting the air chamber to the exterior of the reed instrument. The transducer apparatus comprises attachment means (202) for releasably securing the transducer apparatus to a mouthpiece (201) of the reed instrument in place of a reed. A reed replacement section (203) has a housing with an abutment surface for abutting a surface part of the mouthpiece which would be abutted by a reed secured to the mouthpiece. An air passage extends through the housing of the reed replacement section (203) from an air inlet (211) through which a player of the instrument can blow to an air outlet (213) through which air blown by the player is delivered to atmosphere, without passing through the air chamber (15) within the reed instrument. A speaker (208) is supported by the housing and delivers sound to the air chamber (15). An air chamber microphone (209) is supported by the housing and receives sound in the air chamber (15). An electronic processing unit (204) has: an excitation unit (101) which produces an excitation signal for driving the speaker (208); a processor (102) for receiving a measurement signal produced by the microphone and for detecting from the measurement signal a musical note played by the instrument; a synthesizer (220) for generating an electronic signal embodying a musical note which corresponds to the detected musical note; and output means (103) for transmitting the musical note generated by the synthesizer to a receiver external of the transducer apparatus. The invention also relates to a system for representing the sounds of a reed instrument having the components of the transducer apparatus, to an electronic system for determining a musical note played by a reed instrument having the components of the transducer apparatus and to a method of practising playing of a reed instrument comprising use of the components of the transducer apparatus.

摘要： Provided are, among other things, systems, methods and techniques for processing an audio signal to add virtual bass. In one representative embodiment, an apparatus includes: (a) an input line that inputs an original audio signal; (b) a bass extraction filter that extracts a bass portion of such original audio signal; (c) an estimator that estimates a fundamental frequency of a bass sound within such bass portion; (d) a frequency translator that shifts the bass portion by a positive frequency increment that is an integer multiple of the fundamental frequency estimated by the estimator, thereby providing a virtual bass signal; (f) an adder having (i) inputs coupled to the original audio signal and to the virtual bass signal and (ii) an output; and (g) an audio output device coupled to the output of the adder.

摘要： A sample library for sample notes, wherein each note has been samples at a plurality of dynamic layers, each note having a main sample and a plurality of impulse response samples. Each impulse response sample corresponding to a deconvolution of the main note and one corresponding dynamic layer sample. During playback of a note the main sample is convoluted with a corresponding impulse response sample to produce a simulated target note.

摘要： The present invention relates to the field of audio recognition, in particular to computer implemented note recognition methods in a gaming application. Furthermore, the present invention relates to improving latency of such audio recognition methods. One of the embodiments of the invention described herein is a method for note recognition of an audio source. The method includes: dividing an audio input into a plurality of frames, each frame having a pre-determined length, conducting a frequency analysis of at least a set of the plurality of frames, based on the frequency analysis, determining if a frame is a transient frame with a frequency change between the beginning and end of the frame, comparing the frequency analysis of each said transient frame to the frequency analysis of an immediately preceding frame and, based on said comparison, determining at least one probable pitch present at the end of each transient frame, and for each transient frame, outputting pitch data indicative of the probable pitch present at the end of the transient frame.
